You should prepare as if the test will be much more difficult; that way you're prepared for everything.

Thanks, zyzzyva980. Another thing I would like to ask is about this topic. Is Glaciers the only topic of Dynamic Planet or is there rotation of topics like the Taxonomy events and Astronomy? If so, what are all the different topics of Dynamic Planet and after how many years does it rotate?

There is in fact a rotation. I believe it will go Glaciers->Oceanography->Earthquakes and Volcanoes->Earth's Fresh Waters or something (I did E and V and Waters ). I think what was it two year rotations?

I'm going to our second Invitational which is on the 1st, at Mesa Robles. My friend who was on the Muscatel DP team told me it was really easy. Should I expect the same level of easiness for the Regional competition or are Invitationals always pretty easy?

For example, if given a table of data titled simply "Glacial Mass Balance" and it gives years, glaciers' names, no units for anything, and a list of positive and negative numbers.... Blah. Are the numbers +/- from each previous year?? As in, if 1995 is -0.07 and 1996 is -0.01, is the total cumulative loss in mass balance -0.08, or -0.01? I originally assumed that it was a cummulative figure given for each years' new losses, so the number given was -0.01 down from the original, but now I'm thinking that doesn't make sense...I'm also assuming here that (-) refers to a loss in glacial mass balance (so ablation>accumulation) but I also want to be sure about that, just in case.

If anybody could help me out in this department, I'd appreciate it, thanks.
